Abstract [en]

Research has been carried out at RISE Bioeconomy into converting lignin to carbon fibres, focusing on melt spinning of kraft lignin to filaments, which were subsequently converted to carbon fibres. New equipment has been installed to improve the properties of the lignin based carbon fibres and now it is possible to produce carbon fibres with equal or even better properties compared with published data on lignin based carbon fibres. For a melt spun softwood kraft lignin that was converted to carbon fibres, the tensile strength had an average value of 952MPa, while the Young's modulus average value was 69GPa. A toy car demonstrator has been produced in a project financed by the Bioinnovation, a research programme by VINNOVA, Formas and the Swedish Energy Agency. The existing roof of the car was replaced with one consisting of a carbon fibre composite, in which the carbon fibres were made of 100% softwood kraft lignin. A lithium ion battery as also installed into the toy car, having a negative electrode containing lignin based carbon fibres
